Division 6 Calculation of the results
United Kingdom
From the mean height (area) of the vitamin E peaks of the sample solution determine the concentration of the sample solution in μg/ml (calculated as α-tocopherol acetate) by reference to the calibration graph (5.6.1.2 or 5.6.2.2).
The vitamin E content w in mg/kg of the sample is given by the following formula:
[mg/kg]

vitamin E concentration (as α-tocopherol acetate) of the sample solution (5.4) in μg/ml
volume of sample solution (5.4), in ml
volume of aliquot taken in (5.4), in ml
